Chicago, IL (SportsNetwork.com) - D.J. Newbill led the way as Penn State came alive in the second half to top Iowa 67-58 in a second-round matchup of the Big Ten Tournament.

Newbill, the Big Ten's leading scorer, provided 18 points and six rebounds for the 13th-seeded Nittany Lions (18-15), who will face fourth-seeded Purdue in Friday's quarterfinals.

Ross Travis scored 17 points on 6-of-9 shooting in the win, while Geno Thorpe finished with 11 points, five boards and six steals.

The fifth-seeded Hawkeyes (21-11) failed to advance despite Aaron White's monster game. The senior had 21 points and 13 rebounds and Jarrod Uthoff contributed 17 points and seven boards in the loss.

Trailing 27-19 at halftime and 32-21 early in the second half, Penn State used an 8-0 run to get within three points. Consecutive Thorpe baskets later on put the Nittany Lions ahead 36-34 with 11 minutes remaining.

Newbill netted seven straight Penn State points to give the Nittany Lions a 49-42 advantage with 7:02 to play.

After a Newbill jumper later staked Penn State to a nine-point spread, a pair of White free throws and an Uthoff trey brought Iowa within 54-50 with under five minutes to play.

Gabriel Olaseni and White each made two from the line to cut the lead to 58-56 with 1:42 left.

Uthoff's jumper bounced off the rim with under a minute to go, however. Travis then came up with a big reverse off the glass and made the ensuing free throw to seal the win.

After shooting a paltry 25 percent from the field during the first half, the Nittany Lions improved to 53.6 percent over the final 20 minutes and limited the Hawkeyes to 21.9 percent.
